MACHINE FOR MAKING STlEREO'TYPE-N'IATRICES.

SPECIFICATION forming part of Letters Patent No. 541,445, dated June-l18, 1895.

Application tiled May 4, 1885. Serial No. 164,318. (No model.)

To @ZZ whom it may concern Be it known that I, JACOB RUPERTUS, a citizen of the United States. residing in the city and county of Philadelphia and State ot' Pennsylvania,haveinvented an Improvement of which the following is a speciticaton.

My invention relates to a class of machines employed for making a stereotype matrix. Without first resort to a composed form made by the ordinary process of setting up type within a printers chase, about and upon which composed form a matrix is subsequently cast or formed.

Heretofore machines of this class have been adapted to form a matrix either by stamping letter dies separately and in succession into matrix material, in such a manner, for instance, as is described in United States Letters Patent No. 20,081, granted April 27, 1858,' to J; McElheran; or else by stamping a previously completely composed line of dies into is set forth in United States Letters Patent No. v52,073, granted January 16, 1866, to J. Paulding. I-Ieretofore also provision has been made for the justification of a composed line line in a matrix, by providing means for Wedging apart the devices which carry the dies, as for instance,in United States Letters Patent No. 72,515, granted December 24, 1867, to J. MacNair. Heretofore again in machines containing radially disposed tiers of die arms carrying dies, all ot the dies of each ot' which tiers are provided with the same letter, of which machines the Paulding is a type, provision has been made for arresting at a proper point the descent of the die arms and for aligning such dies ashave been dropped to pressed. Heretofore moreover, in a machine patented December 1 6, 1879, in and by United States Letters Patent- No. 222,642, granted to J. H. Oberly,'trustee, upon an application of J. IV. Schuckers, which machine is an improvement upon that class ot' which the Paulding is a type, provision is made for the-redistribution in their carrying frame, after being dropped, of particular die arms, by the radial elevation of such arms, without resort to the 'arms are contained in a supporting case or frame having a series of separate holders for 6o the die arms, in Which provision is made for arresting the descent ot the arms at a given point, and for aligning a composed line of types or dies-in which also provision is made for the employment of a type-setter, so called, 6;

or, more properly, a key board containing one key for each tier of die arms, which key board is adapted to be advanceda by hand so as to bring its keys successively in range to encounter succeeding dies' in the tiers,i11 which, 7c finally, the matrix is adapted'to be raised against the face of the composedline of type dies so as to vtake the impression of said line,- and my said invention is an improvement upon the said Paulding machine and likewise 75 upon said Schuckers machine.

The object of my invention is the production of a machine for making a stereotype matrix in Whicha greater numberof tierscf die arms can be employed, in which the operation 8 n of composing. the line of dies is more certain and rapid, and in which the impressionin the matrix is more accurate than that formed by any machine of this class of which I have knowledge.

The above objects I accomplish by mech- .anism, a good form of a convenient embodiment of which is represented in the accompanying drawings, and described in this speci- Iication,theparticularsubjectmatterclaimed 9o as novelbeing hereinafter delinitely specified.

Generally stated, my invention vcomprehends improved constructions of the traine Work of the machine (which is made semicircular and adapted to contain at least twice as many tiers of die arms as heretofore possible), of the cases for containing the tiers of die arms, ot' the die arms themselves, of the typedies, and of the means for securing the retention of the die arms in their elevated pome sitions.

It further comprehends a new andv useful key board `the respective keys ot whiehconf trol, respectively, all ofythe die armsfin par-A, ticular tiers of. die arms, together with automatic mechanism by means ot' which the depression of any key in the board is caused to occasion the advance ofthe key boardas ,ann entirety, so as to cause its keys to succcsively operate upon each one of the die arms in all' of the tiers of die arms.

It further comprehends an improved mode.. `of applying the type dies to the die arms,

and an improved distributing mechanism for. simultaneously elevating or redistributinglto their normal position such die arms as have been dropped.

It further comprehends improved devices for justifying a `composed line of, type dies, and the, application. otl such.` justifying de,` vices to diearms.

It further comprehends an i1npreyednleargls4 for aligninga composedline ot'ktypedies, ini? proved justifying.contrivancesand improved, means for holdingdown a composedfaligne and justified line of typekdies and for impress ing the matrix againstsaidline, together` with improved means forwadvancingior lfeedi ing the` matrix.

It further comprehendsa meansforyinsun ing the accnratedeposit oi a descending vtype die, and a" means for `enabling theopelator vto,l detect` errors in the composedline beforethe said line is impressed in thematrix,` A

Figs. 3 to 6, inclusive, 24 to 27, inclusive, and 42 to 45, inclusive, ar drawn Lfull sized.

The Framework.

In the-drawings, Ax, Figs. 1, 2, 7, S, 9, 10, 11, 14, 15, 19, 20, yand 21,-is an elongated horizontal base plate from Which-are erected two semicircular parallel iiat plates of metal, which I term the front frame plate A, and the rear plate A.y

Vhile I specifyscmi-circular framelplates, itis proper to qualify by sayingthat so long as the top portion'of the said plates -is semicircular or provided with a semi-circular ridge or rest for the distributer, the form of said plates -is notv of the essence of the invention.

B B', Figs. 1, 2, 28, 29, 30, and 4l, are respectively a front and a rear series of frame posts, erected respectively from the front and rear frame plates, and extending radially upward and outward from said plates. At their outer extremities the-opposite posts of the two series are connected by transverse crossbars b upon which are mounted grooved pulleys 19X for a-purpose explained hereinafter.

G- C are respectively front and rear rods which together constitute a supplementary frame work, and which rise respectively from the extremities of the base plate and connect together circumferentially the outer extremities of the frame posts. y

Eiected from the baseplate within the arch formed by the frame plates are two parallel standards D D which I term gate standards, and which are respectively provided with ways d d within which the gate Ev is adapted to travel.y Transverselyacross between the standards and longitudinally acertain distancebeyond them in both directions, the base plate is slotted out or cut away as at a2, to admit of the operation of the various devices for aligning, justifying, and holding down the dies and forimpressing the matrix. Depending from the base plate are four bearings F F F2 F3, in which: are horizontally journaled the plunger shaft G and the master shaft H, whereof hereinafter.

I, Figs. 1, 2, 7, 8, 9, 10, 11, 13, 16, 17, 18, 22, and 23, is a horizontally disposed cylindrit'orm table which is preferably a shell inclosed atits ends and made in two sections,and the axis of which is concentric with the plunger shaft as shownv in Fig. l1. This -table is se-v cured both to the base plate and the depending bearingsby the screws i, or inany other convenient manner, and serves to sustain the traveling matrix-J, which is a strip of any suitable or properly prepared material.

The base plate, frame plates, frame posts, cross bars, supplementary frame work, gate standards, depending bearings, and cylindriform table, together constitute the frame work` proper of the entire device.

The Die Arms.

K are the-diearms, a seriesjof radially disposed tiers of which pass through and are contained, so to speak, by a series of radially disposed die armcases Lcorresponding innumber to the number of tiers employed and secured between the frame plates of the frame work.

Each die arm is ofthe form represented i-n Figs. Sand 4 and carries a type or die 7o, Figs.Y

3, 4, 5, and 6, upon the lower or impression surface of which is formed, forpurposes ofimpression, a character or letter.

By reference to Fig. 1 it will be seen that a series of seventy-four tiers of dieI arms arel contained in the machine therein depicted.

Each one of these seventy-four tiers 'is composed 'ot a series of separate and independent die arms averaging in number thirty, although some tiers contain but twenty arms, and some contain forty, the number depending upon the breadth of the die with which the arms of said series of arms are equipped (each die arm of a given tier being provided with the same letter or character),the letter w, for instance, Fig. 6, being of greater Width than the letter i, Fig. 5. Each die arm of the seufries of each tier is aligned from front to back IOO IIO

arms to the right. of the center may in like f ate the justiers and when the plunger has risen to force the matrix against the dies. Fig. 19 is a top plan View similar to Fig. 15, representing, however, acompletely composed and justied line of type dies in the positions which they occupy when an impression is taken from them. Figs. 20 and 21 are transverse vertical sectional detail views of certain ot' the parts represented in Fig. 10, in Fig. 2O a line of type-dies beingshown in the act, so to speak, of being composed, and Fig. 2l representing a completely composed and justified line in the position of the parts when an impression is being taken in the matrix from said line. Fig. 22 is a front elevational fragmentary detail of a part of the cylindriform matrix-table, representing the devices for occasioning the advance of the matrix upon said table. Fig. 23 is a transverse sectional detail through certain of the parts represented in Fig. 22, section being supposed in the plane of the dotted line l l of said Fig. 22. Fig. 24 isafrontelevational view of one of the justifying-blanks and its spreading-bar. Figs. 25 and 26 are top plan views ot the same, the parts in Fig. 25 being in their normal position4 or that represented in Fig. 24, while in Fig. 26 the spreading-bar has been advanced in the manner of its advance for justifying. Fig. 27 is a transverse sectional view in the plane of the dotted line l l of Fig. 24. Fig. 28 isatraginentary front elevational view of the left-hand side of the front frame-plate of the machine, of -a part ot the keyboard-frame, of a part of the distribnter, and of certain of the left-handed tiers of diearms, certain of the devices for occasioning the advance of the keyboard being also represented. Fig. 29 is an end elevational view of the parts represented in Fig. 2S, sight being taken in the direction of the arrow in said Fig. 28, and the parts being represented in the positions which they oc cupy previous to the operation. of composing a line of dies. Fig. 30 is a fragmentary end elevational view of certain of the parts represented in Fig. 29, the key-board, however, being represented in the position which it assumes after it has been advanced to a 4predetermined extent, a part of said keyboard being also represented in section so as to more clearly illustrate certain of the devices for occasioning its automatic advance. Fig. 3l is a front sectional elevational view through the keyboard-frame, section being supposed in the plane of the dotted line l l of4 Fig. 20, and the view being especially designed to represent a good form of ratchetframe and the ratchet-fingers which actuate the sa1ne,rcpresenation being also made of the con trivances for occasioning the predetermined advance of the keyboard. In this View all the parts are at rest or in the position which they occupy in Figs. l, 2S, and 29.

Figs. 39 and 40 are diagrams explanatory of the actionot certain keys and parts connected therewith in the release of die-arms respectively in tiers of twenty and of forty. Fig/ll is afront sectional elevational view through certain of the die-arm cases and tiers of die-arms of my machine, representing the action of the parts which control the said die-arms when in the act of operating for the composition of a line of type-dies, representing, also, partly in dotY ted lines, the die-arm distributing mechanism both in and out of action. Fig. 4.2 is a fragmentary sectional top plan View through the two die-arm caseswhich are represented to the right of the center in Fig. 4l, the section being supposed just above the bottoms of the cases, and the two cases being respectively adapted to contain tiers of forty and twenty die-arms. Fig. 43 is a top plan View, partly sectional, of the two die-arm cases represented in Fig. 42, the sections being taken close to the tops of the said cases and through the transverse diaphragms which separate the said cases in the region of the radial grooves with which said diaphragms are provided. In this View the key-stems and their sheaths are represented as broken away to illustrate the disposition of the parts which they would otherwise cover, certain of the triggers and trigger-springs being thus er posed, while certain of said triggers are represented in section. The View also shows a portion of the keyboardframe. Fig. 44. is a transverse end elevational View into one of the die-arm cases, sight being taken against the face of the comb spring-plate and against ICC 'ITO

manner be supposed provided with an alphabet in lower case, with the' exception of the end tiers of die arms Aupon each side which are provided with justitiers. The remaining twenty tiers may be provided with numerals and punctuation marks.

Before the operation of the machine all of the die arms are lifted and retained, by means hereinafter described, in their cases in the po sition represented in Fig. l.

Each die arm is preferably formed of a sin gle piece of wire bent upon itself in such manner as to form the inverted elongated U shown in Fig. 3, so that the die arm is in effeet longitudinally slotted. One of the ends of said bent wire terminats abruptly at a point above the type die, and ashort distance above said end that side of the wire is bent out to form an off-set kx, or edgewise outwardly projecting portion. The other end of the bent wire is longer and preferably flattened into a yielding or spring-like portion 7c', which is at its terminal extremity provided with a cy.- lindriform knob k2 for attachment to the type die. y

The Type Dies.

Each type die la is T shaped, that is to say, formed of a crosshead 7a3 and a leg 7a4. The upper and under surfaces of the cross head and under surface of the leg are best all parallel, and the edges of the leg are likewise parallel and best right angular to the under surface of the cross head. of the leg is provided with the projecting type or character. One of the ends of the cross head terminates in a circular lip fc5 through which is drilled or punched a hole cout from which is radially cnt a slot k7.

Each type die is connected to its die arm by'having the cylindriform knob and the adjacent portion of the yielding end of the die arm respectively entered within the hole andformed with their circularlips upon the right hand side of their crossheads; while the type' 'dies which are connected with such die arms as are disposed to the left of the center frame posts, are constructed with their circular lips upon the left hand extremities of their cross head, as will he best understood by a reference to Figs. 5, 6, and 4l, and I therefore, for convenience, term the type-dies right and left handed dies. AOf course all of the types or characters which the respective right and left handed type dies carry face in a commonl direction, that is to say,in the machine as represented in Fig. l, with their heads or the up- The under surface f per portions of their types to the right hand side of the machine. The object of this construction and mode of application of the dies is to render it possible to use tiers of arms radiating from opposite sides of a central vertical plane, and for the gate to descend alike upon the upper surfaces of the cross heads of all of the dies of a composed line, without possibility of encounter with the die arms, whereby I am enabled to use twice the number of type dies otherwise possible.

All ofthe type dies, whether right or left' handed are of the same depth from top of cross piece to impressing face of type, that is to say, their impressing surfaces, wlen the type dies are aligned, are in acommon plane, which is parallel with the plane of the surface of the base plate of the machine. All of the legs of each of the die arms, whether the latter be right or left handed, are, likewise, of the same breadth from side to side whatever may be their thickness, so that the'aligning jaws operate alike upon all Vof the type dies.

As already stated, the thickness of the type dies varies with the form of the letter or other character'which they respectively bear, so that wide letters or numbers are mounted upon thicker type dies than narrow letters or numbers, and, as also stated, in consequence thereof, certain of the tiers ot' die arms contain a greater number of arms than others;-

" but, whether the type dies be thick or thin,

impression they are adapted to be compacted,l

aligned and retained together as a compacted line of composed type dies, which, when viewed from the side, as to their cross heads and legs, present an identical outline. Each type die upon its upper surface or cross head is provided with a representation, facsimile, duplicate, image, or portraiture of any desired character, of the letter type or character with which its under surface or leg is provided, in order that when a line of dies is deposited or composed the operator may by the simple inspection of its upper surface detect any error in the composition. This constrnc tion is illustrated in Figs. Lt8 and 49, and is of material importance. Y Itis perhaps in point here to state tha when I employ the term type dies generically, I include the 'justifying devices which are, as will be presently understood, germane in many particulars to the type dies.

The Die Arm Cases.

v. A reference to Figs. l, 28', and 4l, will show that each tier of die arms is disposed radially with respect to the transverse central line of the bed plate, which I term the composition line, and which is parallel with and centrally beneath the bottom ofthe gate Eand that the descent of any particular die arm, whereof hereinafter, will bring the type die which said arm carries down to said composition line.

IOO

IZO

Ordinarily, as stated, all of thediearms of all of the tiers are retained in the elevated position shown in Fig. l. Each tier passes through a separate and independent die arm case, as I term it, suitably constructed and supported conveniently between the front and rear frame plates of the frame work. Each die arm case, being preferably of the construction hereinafter detailed, may be said toiradiate from the said composition line; and each die arm case is adapted not only to receive and in a certain sense contain a tier of die arms, but also to containmeans forattording such support to each die arm of said tier as is essential to secure the proper transverse and radial alignment of all the diearmscomf posing a given tier, not only wheny in` a position of rest but alsoin their action of dropping or gravitative descent. Each case also serves4 to containtheinstru mentalitieswhich maintain the die arms in their normal orA ele; vated positions, as well as the instnumentalities'which release given diearms and permitl their gravitative descent; and incidentally the cases serve to stiften the framel plates. Many constructionsof the casesn as such may be resorted to. of simplicity and economy, to construct the cases` in the following manner: seriesof sectoral end platesl of allength preferably equal,

to the depth of the frame plates, and-of. ,Such proportions as to lieside by side against the inner sides of the frame plates, Figs, 41 and,

42, are assembled ini segmental; relationship and constitute the en dslot' a givenlseriesA of cases. Theseplates are suitably secured, as

for instance by bolts as shown in Fig. 42, to

the respective frame plates.

Each caseis not entirelyclosed at itssides, but the cases are divided by transversediaphragms Z2 preferably castl asA a part of the sectoral enfl plates and extending from the top` of` said end plates to a` depth approximately of half ofthe case. Each opposite pair of sectoral end plates isthus connectedby a trans-` verse-diaphragm, and is also connected at its base by a bottom plate Z3 and lilewisenby a particular case which contains thetier of` The striding of`|` the` which itgiis a member. die arms upon the diaphragms serves to Ias sist in `maintaining the radial setgofieachtier of die arms.

The slot ZS in each frame plate is long enough to take in the shorter legs of all of the die arms in a particulartier, and broad enough topermit of the free gravitative descent of the diearms` notwithstanding the additional thickness which the off-sets la confer upon 16, 17, andlS, thatY when a sufficient number of` diearms` have descended to form a composed lineofI type dies., the die arms which are connected with right handed type dies radiatefroml adiftierent transverse linethair thatfrorn which radiate thedie arms con-` nected with the leftL handed type-dies, and

Now/the linesfrom which the respective right andilcft handeddie arms radiate are respectively the two centers from which the so-called semi.- circl'ilanor arc-shaped frame plates spring, the saidframe plates not` being continuous` arcs or. semi-circles, but` being, in fact, two segments which are centrally connected by aistraighttand not segmental portion, Ldeemit properito mention the above fact, solthat` it may be understood why the die arms do not in fact descend to acommon center. When the-die arms, are elevated or in a position rof rest, the type dies are exposed alittle belowthe frame platesof the cases, while the upper extremities ofthe armsextend to a,considerable.distance above the cases, as shown inv Fig. 1.

The projectionof the die arinsabove the cases is such aste allow of a suilicient descentl to bringthe type diesinto horizontal coincidencewjth the-.composition line at the `base plate. The radial distance to which the type dies must be elevated is determined, measurably, by the shape of the type dies themselves, t.

IIO

and the extent ot' radial elevation is such that when all of the dies are elevated they clear one another as shown in Figs. l and 4l.

.The Triggers Controlling the'DL'e Arms.

The bottom edge of each diaphragm is provided with a series of parallel radial equi-distant ribs Z9, preferably made by slotting, the

slotted grooves or spaces between which arev aligned below the grooves Z6 of said diaphragm, and serve to permit the passage of the shorter legs of the die arms. The oflce of these ribs is to serve as supports for the fulcra ot' a set of triggers c, Figs. 41,43, and 44, one of which triggers is placed in the groove between each adjacent pair of ribs Z, and all ot` which are fulcrumed upon a rod or Wire c2 which preferably is continuous through all of the ribs Z9.

The triggers are levers of the rst order and fulcrnmed at about their centers. The lower arm of each trigger is controlled by a spring Z5, Figs. 4l, 43, and 44, all of the springs being preferably formed as a single comb spring plate, as will be best understood by a referL ence to Fig. 44.

The normal or elevated set of the die arms, Fig. 4l, is maintained by the frictional contact of the lower arm of the triggers with the off-sets leX of the die arms, the said contact being due to the stress ot 'the springs, which is constant.

It is obvious that a deflection of the upperV end ot' a trigger against the resistance of its spring by a force sufficient to overcome said resistance and deliect the lower end of the trigger, will permit the release of the die arm controlled by said trigger, and, as there is no other opposingr instrumentality, its full gravitative radialdescent.

The devces'which occasion the above deilection of the triggers are connected With and controlled by the keys of the machine, and will be presently described.'

The end of each triggeris provided with an overhanging stop c3 which, after the descent ot` a particular arm, as shown in Figs. 4ll and 43, prevents by contact with the radial rib which is adjacent to it, the deflection of said lower end ot' the trigger by its spring to van extent sufficient to cause said trigger to bind against the die arm and so arrest its descent.

The purpose of form-ing the offset on the' The Finger Keys.

Transversely across the top of each die arm case isinserted and fixed atubular sheath c4, Figs. 41, 43, and 44, the chief ofce of which is to serve as aslidebearing for the key stems.

'The form ot these tubular sheaths is best shown in Figs 4l and 44, and they are botto mless, so to speak, in order to permit the longitudinal travel and rotative throw ct' the trigger lugs c5 which are mounted upon the key stems'm.

M are the keys, disposedin the are of a eircle in an assemblage constituting, in popular phrase, lthe key board ot the machine. These keys are provided upon their linger portions With letters or characters cdiiespondig to the letters or characters with which the respective tiers of thetype dies of the die arms are provided. Each key is a lever and is mounted upon a particular key stem which passes through a particular die arm case and is housed therein in the tubular sheath thereof.

Reference to Figs. 1,28, 29, 30, and 43, will indicate that the'keys are disposed in a segmental nest soto speak, or rather in twov nests respectively right and left handed, each key of each nest` inclining toward its neighbor and presenting 'its linger portion approximately level to the pressure of the fingers. Normally the keys stand in such inclination that their ngerportions presenta con tinnous arc, as shown in. Figs. l, 2S, and 29. Depressionof a particular key throws its finger portion out of the line of this arc, while upon' its -release it is controlled, as hereinafter explained, to instantly resume its former position.

Each key, through the instrumentality ot its stem, is adapted to control all ot' the die arms in a particular tier, and this is accomplished by Virtue of a trigger lug c5 with which each key stem is provided, and which is in range for an engagement controllable by the TOO key, with the upper end of any particular trigger in agiven case opposite Which trigger the said trigger lug is for the time being caused to stand.

For better explanation, I would here state that the line of type dies which itis desired to set up is composed from the rear to the front of the machine and along whatI have termed the composition line of the' base plate, and that the die arms are selected and dropped from the rear of the tiers forward to the front.

The Kez/ Board Frame.

Now as each die arm case is provided with its own key stem operated by a particular key, and as each stem has but a single trigger lug, itis obvious that, if the said trigger lug isto do duty in controlling the release of all ot' the die arms in a particular case, it will be necessary to provide means for securing the uniform but intermittent simultaneous advance from the rear -to the front of all of the said cases of all of said trigger lugs and the said key stems which carry them, so that the said trigger lugs may intermittently but successively face and be in range for engagement with each one of tbetriggersinthe said cases. This is accomplished by mounting all of the IIO keys and their connected key stems, in a key board frame, herein sometimes termed the key board, which is adapted intermittently but constantly under the actuation of any one of the keys to advance from a rearmost normal position at starting (forward) to an extent suthcient to cause the sweep or advance of all of the trigger lugs throughout the enr tire length or depth, so to speak, of the cases, and past each trigger,-it being borne in mind, of course, that the key stemspass completely fore and aft,7 so to speak, through the cases and that in their position of rest before starting they are preferably of such length as to project to the rear of the cases to a considerable extent, as shown in Figs. 2 and 2f).

The key board frame is preferably com posed of two upright parallel arcshaped segmental plates N N Figs. 2S, 29, 30, and L13, which are connected together at their extremities and at. the center by tubular boxings n, the two end boxings being respectively mounted and free to travel in and out upon horizontal studs 11.2 secured to the frame plates and projecting to the front therefrom. The segmental plates N N are parallel with and stand im mediately in front of the frame plates A A. The stems of the keys pass through and journal in the said segmental plates as shown in Fig. 43, and it is obvious that, when the said key board frame is moved in and ont upon the studs on which it travels, the key stems and keys move in and out with it, and that therefore whatever in and out movement is imparted to itis likewise imparted to the said keys and stems.

'When the machine is in the position represented in Fig. 1 and ready to be operated upon, the key board frame is in the position represented in Figs. 29 and 43, that is to say in to the full extent of its movement upon its studs. In this position the trigger lugs upon the key stems are slightly to the rear of the rearmost triggers of cach tier of triggers, as shown in Fig. at.

The Ratchet Frame.

Now it is necessary that the depression of any key in the key board should occasion two results: first, the advance of the keyboard, keys and stems, and trigger lugs, to an extent suiiicient to bring the trigger lugs in front of the rearmost triggers, and, second, the deflection of the trigger which the trigger lug of the key depressed is caused to face, so that a type die and die arm of the tier of the key struck may be released and descend. The second of the above results is accomplished by the completion of the rotation of the stem ot' the key depressed, the filial rotation of said stem causing the trigger lug with which it is equipped to deflect the trigger it is caused to face, as one of the lugs is shown as doing in Fig. 41; but the first above result, of occasioningapredetermined advance of the key board, keys, and stems, is accomplished through the instrumentality or intervention of what I term a ratchet frame O, Figs. 2D, 30, 31, 32, 33, 34:, and 35, the same being a segmental plate of approximately the same dimensions and of the same curvature as the segmental plates of the key board frame, which is mounted and supported between 'the said plates upon a ratchet shaft P Figs. 1, 2S, 29, 30, 31, 32, 33, 34, and 35, upon. which it is sup ported, conveniently through the intervention of the grooved wheels o', so as to be capable of a limited end for end travel thereupon. Support is also afforded for the said ratchet frame by a transverse web o2, Figs. 3 1, 3G, and 43, which covers and has a movement over the central tubular boxing n of the key board frame. At its lower, and in the apparatus shown, left hand extremity, the said ratchet frame is provided with a pivoted pawl 03, Figs. 28, 29,30, 3l, 32, 33, 371, and 35, which on its under surface is provided with an angularly disposed tooth o" adapted to engage with the angular teeth of a ratchet Wheel p mounted upon the extremity of the ratchet shaft P. The pawl is controlled in such manner that its tooth is normally in bite with the teeth 0f the ratchet Wheel by a spring o5 coiled about its pivot pin o6 and bearing as to its operating extremity upon the pawl near its handle 07. The pivot pin of the pawl is housed in a suitable bearing formed in the extremity of the ratchet frame, the said frame being conveniently bent over upon itself as shown in Figs. 2S, 30, 31, 32, 33, 34, and 35, not only for the purpose of forming bearings for the pivot and grooved wheel o', but to form a sleeve o8 for encircling the ratchet shaft P. Both ends of the ratchet frame are bent over to form the sleeves for the said shaft, but one extremity only is shown as provided with the pivoted springcontrolled pawl. The ratchet shaft has its bearings in the two lateral tubular boxings n by means of which the key board frame has its in and out movement, and the said boxings are slotted to contain toothed spur wheels p', which are tixedly mounted upon the said ratchet shaft, and are respectively in engagement with racks pzlet into the horizontal studs n2, as particularly illustrated in Figs. 2D, 30, 31, 32, and 33.

interposed between the inner face of the tubular boxings n, and the exterior face of the sleeve o8 formed upon the left hand extremity of the ratchet frame, is a spring p3 coiled upon the ratchet shaft, the office of which is to throw to the right hand or return the ratchet frame after it has been moved laterally to the left hand, as hereinafter explained.

Now it is obvious that, if a movement` be imparted to the ratchet frame from the right to the left hand of the machine, the tooth of the pivoted pawl which is in engagement with the ratchet wheel will occasion a predetermined backward rotation of said ratchet wheel, and consequently a corresponding rotation in the ratchet shaft and the toothed spur wheels with which said shaft is equipped,

IOC

IXO

' horizontal studs n2 a predetermined advance of the key board frame work will be secured that so soon as the force which is employed to move the said ratchet frame from the right to the left, ceases to exert itself, the expansion of the spring p3 will serve to return the said ratchet frame from the left to the right, the toothedspring pawl during such return rising out of the teeth of the ratchet wheel with which it has been engaged, the said wheel, by reason of the weight and inertia of the key board frame and connections as an entirety, remaining at rest, but, after the completion of the throw of the frame under the stress of its pawl spring, re-engaging with another tooth of the said ratchet wheel. The above throw of the ratchet frame, it will therefore be seen occasions a predetermined outv ward movement of the key board frame, ratchet frame, and connected devices, and of the keys and stems. This predetermined advance is calculated, by the inclination of the teeth of the pivoted pawl and ratchet wheel,

-to be such as to occasion an advance in the key stems and the trigger lugs sufficient to cause all of the trigger lugs to face either, at the first movement, the rearmost triggers in the die cases, or, at subsequent movements, triggers in advance of those which the said lugs immediately before said movement faced or were in range to act upon.

The Ratchet Fingers.

The means which I adopt for securing the throw of the ratchet frame from. the right to the left hand, are a series of ratchet lingers mx, one of which is secured to each key stem at a position necessary to cause them to-bear against suitablyformed abutments m2 formed in or applied to theratchet frame.

The ratchet fingers may be of varying form and length, and are shown in Figs. 3l, 32, and 33 as acting upon abutments shaped in the substance of the ratchet frame itself, as a reference to the said figures will make clear, and the set of said ratchet fingers upon the key stems is intentionally such that the very first movement of depression of a particular key causes the ratchet finger of the key stem of said key at once to act upon an abutment of the ratchet frame, so that the right to left throw of said frame is accomplished before the trigger lug `upon the said key stem acts upon the trigger with which, for the time being, it happens to register.v y

lt isobvious that the abutments, so called, are simply points of resistance upon the ratchet frame, against which the fingers may bear, and that it is inconsequential whether the said abutments be formed in the frame itself, as represented in Figs. 3l, 32, and 33,

shown in Fig. 36.

In. either of the foregoing constructions, or in any analogous construction, it is of course necessary that the key stems should either actually or in effect pass through the ratchet frame, and that the ratchet frame should be sufficiently slotted to permit of its free movement from right to left Without encounter against any other stem or finger than that the operation of which is occasioning the then movement of said ratchet frame, as a reference to Figs. 3l, 32, 33, and 36, will make clear. The return rotation of the key stems and consequent return of the keys to normal position is best accomplished by the application of what I term a key spring lm3, `which is coiledv about and connected with the key stem, and alsol secured to a fixed point upon, for instance, the front segmental plate N of the -key board frame as shown in Figs. 37 and 38. It will also be observed that in a machine constructed in exact accordance with that shown in these drawings, the trigger springs Z5 exert., upon the relief of pressure by the trigger'lug upon the trigger, a sufficient influence in deflecting the trigger to the extent that its overhanging stop c3 will permit, to occasion a reverse throw by the ytrigger of the trigger lug and key stem, and so to bring the ratchet finger of the stem under consideration into a position in which the recoil of the spring p3 on the ratchet frameacting through said frame and itsabutment upon'said finger, will occasion the complete return rotation of said key stem and the return of the connected key to its normal position. Of course, in a position of rest before action,the ratchet frame under the inuence of the spring p3 stands to the right to the full extent of its movement in -that direction, as shown in Fig.

IOO

3l, and in this position, its throw being limited IIC gle trigger lug, is made to do duty to control the drop of any one of the die arms contained in a given tier of die arms in a given case; and also how the predetermined intermittent advance ot the key board frame work, ratchet frame, keys, and stems,-occasioned, as already explained, through the movement of any key,-is the means by which a trigger lug on an intermittently advancing Akey stem is caused, step by step so to speak, to force, and, if desired, control the drop of each one of the die arms in the tier which it controls.

The employment of two racks in the studs, and of two spur wheels mounted uponthe same shaft, insures the simultaneous and even advance of the key board frame, and prevents any warping or twisting of the latter and any consequent binding upon the studs on which it travels. The key board,

after having' been advanced by the play ofthe keys to the full extent of its forward movement, can be returned either by hand, the spring pawl being, of course, lifted and held out of engagement with the ratchet wheel; by a spring connected with it and with a fixed part of the frame work; or, it desired, by a counterweight, or kindred contrivance, as will be obvious to any mechanic.

I have already mentioned that some ot' the type dies are of greater breadth than others because some letters are broader than others. As, however, each tier of die arms is of the same depth as every other tier, it is obvious that some tiers will contain a greater number ot die arms and type dies than others. In the drawings I have represented the tiers as respectively containing, in some instances, twenty, and, in other instances, forty die arms and dies. Now, as all of the trigger lugs are placed at a corresponding point upon their respective stems, it is obvious that those lugs which actuate the triggers controlling the thinner dies must be no broader than the breadth of a single trigger applied in connection with a die arm in a tier ot forty die arms, as otherwise such a broad lug would, upon the rotation of its stem, operate upon two triggers simultaneously, and so release two die arms. I have, therefore, made the trigger lugs upon the key stems ot keys controlling tiers of forty die arms of the breadth of a single trigger in such tier, while I have made the lugs which control the triggers of tiers of twenty die arms of twice the breadth of the lugs of triggers of tiers of forty, as well as of twice the breadth of the triggers in tiers of twenty. `New it will be readily perceived that, all the triggers being of the same breadth, a broad trigger lng controlling a tier of twenty die arms must, in order to actuate a trigger next in advance ot' that trigger upon which I suppose its action of trigger-release t0 commence, advance twice the distance, in the outward movement of the key hoard, that a trigger lug in a tierof forty die arms 1n ust advance fora kindred purpose; and it will therefore be apparent', as a given advance ot the key board occasions an equal advance in all the key stems, that such advance as brings a broad lug to bear against a triggerin advance ofthat trigger which the said lug immediately before presented against, will occasion a coextensive advance of a narrow lng, or, in other words,st1ch an advance of said narrow lug as will occasion it to skip onc of the triggers which it. might otherwise control; whereas, upon the contrary, such an advance of the key board as will occasion a narrow lng to move from a given trigger in atier ot' forty to the next trigger in advance, will occasion a co extensive advance in a broad trigger lug, or an advance not equal to the full distance (trom center to center) of adjacent triggers in a tier of twenty. As, however, in a tier of forty a predetermined advance of a narrow lug occasioned by its own key, will also bring t tier ot' forty in which said trigger plays. i Fig. 33, on the other hand, a long ratchet finthe said lug into range with a given trigger next in advance of that last acted upon, and as the same extent ot' advance of a broad lug will bring the latter by reason ot' its breadth into position to control a next in advance trigger in a tier of twenty, it is obvious that it is immaterial as to the control of all of the keys upon the particular tier of die arms with which they happen to be connected, whether the advance of the keyboard be co-extensive with the distance apart oi` adjacent die arms in tiers of forty, or co-eXtensive with the distance apart of adjacent die arms in tiers of twenty, inasmuch as, in either case, the trigger lug of a given key, be it a narrow or a broad lug, will always be in range to engage one I trigger only of the tier with respect to which it operates. y broad trigger lugs which control tiers of New, as it is necessary that the twenty, should advance, upon each depression of the key controlling them, the full distance apart of the die arms in said tiers of twenty, it is obvious that provision must be made t'or advancing the key board frame upon the detlection of such a key, twice the distance that it is necessary to advance said key board upon the detlection of a key controlling a trigger in a tier of forty. Such result I accomplish by providing the key stems which control tiers of twenty with ratchet lingers of greater length than the length of thelingers ot' stems controlling tiers of forty, as a reference to Figs. 31,32, 33, and 3G, will show, the said longer lingers being adapted to bear against abutments ot' suitably conformed outline to occasion a throw ot the ratchet frame t'rom right to left of twice the horizontal distance which it is necessary to throw said frame in order to occasion the advance of the key board to a horizontal distance correslionding with the distance apart of triggers in tiers ot forty and of twice the longitudinal extent to which it is thrown by the shorter ratchet tingers, which, as stated, are shown connected with the key stems controlling tiers of forty.

To further illustrate, in Fig. 32 a key stein `controlling a tier of fort-y, provided with a narrow trigger lug and withv a short ratchet tinger, is shown as having been operated,by the depression ot the key connected with its y stem, to have thrown the ratchet frame to the t left to an extent which isapproximately equal to, for instance, half the breadth of the toot hed i face of the ratchet wheel,-the throw in con sequence having resulted in such a rota-tion `of the said ratchet wheel and its connected spur wheels as to have caused simply such sutticient advance of the key board frame as to have occasioned the advance ot the narrow trigger lug ot' the stem in question from one trigger to the next trigger in advance in the In ger connected with a key stem having a broad trigger lug and controlling a tier of twenty, is shown as having, upon the defiection of the key connected with its stem, moved the ratchet IIO frame to the lett a horizontal distance which is approximately equal to the full breadth of the toothed face of the ratchet wheel, and which is twice as great as the horizontalmovement represented in Fig. 32 as having been imparted,-the said horizontal advance shown in said Fig. 32S having occasioned a rotation of the ratchet wheel twice as great as that supposed occasioned by the movement represented in Fig. 32, and having consequently occasioned, through thetoothed spur wheel and rack, an advance of the key board frame of twice the extent of that occasioned by the movement of the ratchet frameillustrated in said Fig. It is obvious, therefore, that it is simply necessary to provide the key stems which control tiers of twenty and have broad trigger lugs, with longer ratchet fingers than the key stems which control tiers of forty and have narrow trigger lugs, and to so conform the abutments of the ratchet frame as to give full effect to the movement which the respective lengths of the said tingers are designed to accomplish,-.in order to secure upon the movement of particular keys such predetermined advance in the key board frame as shall insure the accurate operation of the trigger lugs upon they triggers of the tiers which said keys respectively control.

Of course, when a key controlling the die arms in a tier of forty is struck it is immaterial whether a narrow trigger lug skip a given triggerin the tier in quest-ion, as, when it stops after such skipping, it stops in front of a trigger which controls a die arm carrying identically the same die as that of the die arm which it skipped; while it is also equally immaterial whether the advance of a broad lug controlling the triggers in a tier of twenty, be its own full breadth and equal to the distance apart of the triggers in such tier, or whether it is simply half such distance, because its own breadth is such that in Whatever position it stops it presents against a trigger which controls a die arm in the tier in question next in advance of that which was last in range of the operation of said trigger lug'. V\7hen,how ever, it is desired to repeat in succession two, three, or more characters with which the type dies in a given tier of twenty are provided, the key. controlling the selected tier is successively struck the desired number of times, each time with the result of occasioning an advance of the key board sufficient to bring forward the broad trigger lug of the key struck to the extent of its full breadth, so so that it successively presents against immediately succeeding triggers controlling immediately succeeding die arms in the tier of twenty in question. The advance of a broad trigger lug to the extent of but half its fu'll breadth is only occasioned when a key controlling die arms in a tier of forty is struck, as is done when itis desired to bring one or more of the narrow characters into action. Vlhen, on the other hand, itis desired to successively repeat a narrow character, a key breadth; while, conversely, as stated, the

touch of a key controlling a tier of twenty, occasions an advance of all of the broad trigger lugs equal to their full breadth,and incidentally an advanceof all the narrow trigger lugs equal to twice their breadth.

To still further illustrate I'have in Figs. 39 and 40 represented, as far as is possible by diagrammatic plans, the above described construction and operation. In these figures the die arms K are indicated by the black disks, and the triggers c by the solid black parallelograms, while the broad trigger lugs are lettered a and the. narrow trigger lugs ax. The left hand tier of die arms in each diagram is a tier of forty and the right handa tier of twenty. In Fig. 39, the trigger lugs a and a* as indicated by the cross-sectionally lined parallelograms, are both to the extreme rear of the tiers which they respectively control, and this is the position the lugs take before the key board is operated upon. I/Vhen then the key controlling the narrow lug ax is first depressed, that lug will advance to the position indicated by the full lined parallelogram ax,

while'the broad lug by the saine advance ot' the key board 'will be caused to assume the position indicated by the fulllined parallelogram a, its advance being but onefhalt' its own breadth, although, as shown, sufficient to bring it opposite the first trigger in its tier. Assume now that the key controlling the broad lug is next depressed. The said broad lug will advance from the position indicated by the full lined parallelogram@ to that indicated by the dotted lined parallelogram a., or its full breadth, and sufficiently far to be in range to engage the trigger next in advance, while at the same time the advance ot the key board will have occasioned the advance of the narrow lng ctx in the tier of forty, to the position indicated by the dotted parallelogram otX representing said lug. I In Fig. 40 the lugs are .represented by the cross-sectionally lined parallelograms a, ctx as, before their advance, in the same position that they at such time occupy in Fig. 39. In this tigure, however, the full lined parallelogram [L indicates the advance of the broad lug, which isassumed to be first-operated, sothat said lug is in range for operation upon the first trigger'of the tier of twenty, while the full lined parallelogram ctx which indicates the narrow lug, shows how, by the said advance of the broad lug, the narrow lug has been caused to skip the first trigger and to register in front of the second trigger of the tier of forty. The dotted lined parallelogram LX which indicates the narrow lug, shows the position of said lug when the latter is next operated, and shows that its advance has been IOC] IIC

trg

simply its own breadth or from the second trigger to the third, while the dotted lined parallelogram a which indicates the third position of the broad lug shows how the latter, simultaneously with the last mentioned advance of the narrow lug has advanced but one half of its breadth.

The extent of advance ot the key board frame occasioned primarily by the impulse and movement given to the ratchet frame by the ratchet fingers, is fixed and determined not only by the length of the ting-ers and the character of their abutment-s, but also by the proportions ofthe ratchet wheel and the pitch and number of its teeth, by the pitch and length of the teeth on the pawl, and by the diameter of the toothed spur wheels, the number of their teeth, and of those of the racks with which they engage,all matters of mechanical construction and adaptation which a skilled workman will readily comprehend, and an operative embodiment of which is represented in the drawings forming apart of this specification.

I have elected to represent and consider tiers of die arms respectively containing twenty and forty arms, and this I have done for simplicity of representation and explanation. It is obvious, however, that, under suitable modiiications, the tiers may be made to contain other numbers of die arms than twenty and forty. Thus one tier might contain thirty, and another sixty, or one ten and another twenty, or by proportioning the various parts which occasion the predetermined advances of the key board and control the retention in their elevated positions of the die arms, the tiers may be made to contain die arms varying in number and not bearing the relation simply of two to one. Thus one tier might be made to contain ten die arms, another twenty,

and another forty, without departure from the principles of construction and operation already at length set forth.

The DstrZ/ute'r.

Having now described the means for securing the retention of the die arms and dies' in their elevated position, and also the means for at will securing the radial gravitative descent of any one ot' the die arms so that its die forms one of the line of dies being composed, it is obvious that means must be provided for the subsequent elevation or lifting of each one of the dies being a member of a given line of composed dies, and the means which I have devised are the following:

Q is a series of levers, Figs. 1, 2, 28, and

I al, compounded and connected together substantially after the manner of construction resorted to in forming what is known as a lazy-tongs. Each lever is connected to its neighbor at top and bottom by the pivots q, while centrallyoverlapping levers are connected by pivots, whichI term lifting bars gx. There are two parallel sets of these lazy-tongs or compounded levers, each of which as a whole is arc-shaped. Through the medium of lever sleeves q2 to which certain of said levers of each set are at intervals connected, the two lazy tongs are mounted to slide upon the frame posts of the frame work, one of them being by such means mounted, so to speak, or superimposed upon thefront frame plate, and the other upon the rear frame plate. Each lazy tongs is provided with its own le ver sleeves, of which those connected with the front lazy tongs ride upon the front frame posts and those connected with the rear lazy tongs upon the rear frame posts. The two lazy tongs are, by means of the lifting bars which pass transversely and horizontally from the central pointof given levers in the front lazy tongs to a corresponding central point in corresponding levers in the rear lazy tongs, connected so as together to form a composite device which, in connection with the cords which control its upward movement, is herein termed the distributer or distributing apparatus,

Each of the lifting bars (1X passes completely through a particular tier of die arms. The die arms, as a reference to Fig. Swill show, have between their legs a longitudinal slot or space which amounts in effect to a contin nous slot through the center of all the die arms of a given tier,and is of the length of said arms.

-The sleeves of the respective lazy tongs may, if desired, be connected by cord bars qs, Figs. 29 and 30, which may or may not, as convenience of manufacture may dictate, be pivots of given levers of the respective lazy tongs. I prefer, however,that these cord bars should be upper pivots of particular-levers of the respective lazy tongs, as in Figs. 29, 30, and 4:1,

they are represented as being. The oliice of these cord bars is to serve as points of attachment for the cords Q4 by means of which the two lazy-tongs and their connected sleeves are raised to secure the elevation of the die arms, as shown in dotted lines in Fig. 4l. A con` venient arrangement of these cords is that shown in Figs. l, 2, 29, and 4l, in which six separate cords are employed, which are respectively connected, two of them to the central cord bars connecting the two central sleeves, and one to each of the four lateral cord bars which connect respectively the end and the intermediate sleeves. 'The grooved pulleys bx which, as already stated, are mounted upon the cross bars h of the supplementary frame work, receive and carry these cords. The central pulley has five grooves, the two intermediate pulleys have each two grooves, and the end pulleys have each one groove. The outside cords, or those connected with the cord bars of the end sleeves, pass rst over the end pulleys which have but a single groove, and then over the intermediate pulleys which have two grooves, and then in opposite directions around the central pulley which has tive grooves. The cords connected with the cord bars of the intermediate sleeves, pass over the other groove of the intermedi- IOO IIO
